Ribbon Length Fraction Model Worksheet gives learners a diagram, one worked example and five questions. The student sheet leaves space to show work. A second printable page gives the steps for each answer.
Start with the model
The strip models one ribbon. The denominator counts all equal parts. The numerator counts the parts you select.
The strip has 8 equal cells, with 3 striped, 2 dotted and 3 blank.
Worked example
There are 3 striped parts out of 8, so the striped fraction is 3/8.
Ask the learner to point to the information used in the example. When they move on to the exercises, have them record the quantity, unit or label that each step represents.
Practice questions
- What fraction has the dotted pattern?
- What fraction has either pattern?
- What fraction remains blank?
- If each equal part contains 4 units, how many units have either pattern?
- Would dividing the same whole into twice as many equal parts change the fraction shaded? Give an equivalent fraction.
Separate answer key
- 2/8. Count the dotted parts out of all 8 equal parts.
- 3/8 + 2/8 = 5/8 = 5/8.
- 8 − 5 = 3 blank parts, or 3/8 = 3/8.
- 5 × 4 = 20 units.
- The fraction stays the same. The combined shading is 5/8 = 10/16.
